vs2017 Geçiş başarısız, ArgumentNullException

Question

Project.json'dan .csproj'a bir çözüm aktarırken, çözümdeki bir proje için geçiş başarısız olur. Verilen

Hata geçerli: Proje benzer project.json içerikli tüm başarıyla taşındı 24 diğer projeleri, tüm içerdiğinden

Migration failed. Unhandled Exception: System.ArgumentNullException: Value cannot be null. Parameter name: version at NuGet.Versioning.VersionRangeBase.Satisfies(NuGetVersion version, IVersionComparer comparer)

Bu hata kafa karıştırıcıdır. Bu hatayı açıklıyor project.json bir şey

Bu tam hatadır nedir?

Answer 1

Geçiş aracını, sürüm numarası eksik olan "System.Runtime": "*",'dan hoşlanmadığı ortaya çıkıyor. "System.Runtime": "4.0.20", değiştirildi.
